Adjusting sample table Z-position

If sample goes too far or too close to the tip during scanning due to drift or other causes, it is possible to lift or to lower it using commands for single-step approach/retraction. To lift the sample on a single step (approaching) you can press button and to lower it to a single step (retraction) you can press .

Note: Mechanics always has some backlash, due to that the table can stand still for the first few steps.
